Basis: phonetics. One voiced obstruent, two sibilants, ends on a consonant. The canon has no entry, so this is the sound of the name and nothing else.

Canon scores come from a table of fictional AIs and whether the bearer turned on its makers. Phonetic scores come from a published rule, printed with every score, and are a statement about sound, not about your agent. How the sound is scored.

As recorded on the Social Security card application. Names given to fewer than five babies of a sex in a year are not published, so the file is a floor.
